CENTRIFUGAL SEPARA'IOIL:

Specification of Letters Patent.

Application filed April 13, 1909. Seriallio. 489,627.

To all whom it may concern:

Be it known. that I, PHILIP M. Srranrnns, a citizen of the United States, and a resident of West- Chester, in the county of Chester and State of Pennsylvania, have invented certain new and useful Improvements in Centrifugal Separators, of which the following is a specification.

My invention relates to centrifugal liquid separators and it consists in providing improved means for insurin a steady rotation of the vessel and a satis actory feed of the liquid thereto.

The invention is fully described in connection with the accompanying drawing, and the novel features are pointed out in the claims.

Figure 1 is a sectional view of a portion of a centrifugal liquid separator having my invention applied thereto. Fig. 2 indicates a slightly modified construction.

The drawing shows only the feed inlet portion of the centrifugal separator vessel 2,,-

and of the fixed casing 3 therefor; the invention relating entirely to such portion of the well known machine indicated, which need not therefore be more fully shown.

'Letters lratent No. 706,088, issued August 5th, 1902, to Herbert McCornack for improvements in shaft mounting, which fully illustrates a machine to which my invention is applicable, shows a frictional steadying device movable laterally with the feed-inlet end of the rotary vessel, the feed supply to the vessel being independent'of such movable device.

The object of my invention is to provide an improved device adapted to serve both as an improved steadying means for the vessel and as a feed nozzle'which is automatically movable with the swing of the vessel so as to insure proper' deliveryof the liquid to the latter. V

' The fixed casing 3 is'provided, as indicated, with a conduit plug 4, communicating with a detachable conduit tube 5, andwith a conduit chamber 6'1n the casing. This chamber, as shown, is formed by a an upwardly-extendin sleeve or tube 7 attached to the conduit-p ug 4, and has a discharge outlet to the rotary vessel which is formed in a movable feednozzle 8 constituting the main feature of the present invention. This feed nozzle; asshown, has a circular rim 9 :which is seated by a spring 14 agamst a Patented Mar. 8, 1910.

flange 10 on the sleeve 7 so that itis capable of a lateral movement againstjthe frictional resistance arising from the sliding contact between said rim and flange. The liquid supplied to the conduit chamber 6, is deliveredtherefrom to ,the feed inlet 11 of the rotary vessel, throu the discharge openin 12 in the nozz e 8; and the latter .is a apted, as shown, not only to automatically adjust itself to any swinging movement of the rotary vessel so as to maintain the nozzle opening 12 inpractical alinement with said feed. 'n at 11' of the vessel, but at the same t me to serve as a frictional steadying device for the vessel ina manner similar to that described in the McCornack patent already referred to. These two functions of the movable nozzle 8, are effected, as indicated, by forming the feedinlet end of the vessel with a countersink or circular recess 20 whereby 1t1s adapted to serve as a nozzlecontactmg ring, in which the nozzle 8 is loosely entered so that the wall of said recess 20 will contact therewithwhenever' the rotary vessel attem ts to swing laterally. To provide for the c ear delivery of the-liquid from the discharge opening 12 in the nozzle,

to the feed inlet 11 of the rotary vessel, said nozzle open1ng12 is-preferably made sufficiently smaller than the mouth of the feed inlet to ermit of a slight inde endent movement .0 the vessel laterally; ut as soon as such swingof the vessel brings the wall-of its recess 201nto contactwith thenozzle. 8, further swing thereof is in the first place, yieldingly resisted by the, nozzle so as to quickly. steady its rotation; and inthe next place thenozzle is compelled 'topartake of' any continued swing of the vessel after such contact, thereby maintainin the nozzle ppefing 12 in alinement wit the feed in To provide-for returning possible leakage .whollyin the nozzle piece as indicated in Fig. 2-. The latter figure also shows a dif-' ferent form of. conduit plug fromFig. 1 we and other modifications ofthe preferredconstruction may obviously be made without departing from the invention as defined able feed nozzle of less exterior diameter than said ring and loosely entered in the latter.

2. The combination with a suspended rotary vessel havin a feed inlet at its lower end, and a supply conduit therefor, of a 5 laterally movable feed nozzle loosely entered in said inlet and having a slide-bearing rim,

a fixed seat for said rim, and a spring arranged to press the same against said seat.

8. The combination'with a suspended rotary vessel having a feed inlet at its lower end, and a supply conduit therefor, of a laterally movable feed nozzle loosely entered in said inlet and forming an annular drip receptacle below the latter arranged in communication with the feed nozzle opening.

In testimony whereof, I affix my signa ture, in the presence of two witnesses:

PHILIP M. SHARPLES.
